In multi-parameter full-waveform inversion (FWI) the choice of parameterization is fundamental to correctly separate the different parameter classes. We investigate the influence of the parameterization on the parameter separation for an elastic isotropic FWI problem from a mathematical standpoint. We also study this influence numerically using a simple model containing multiple anomalies in each parameter class positioned at different locations.
